Abstract
A natural filter for ecological systems is provided. The apparatus includes a rock medium container for holding rocks for filtering life, means for circulating water, means for floating the apparatus, and means for supplying sunlight to the filtering life and the normally unreachable depths of water. This natural filter maintains a healthful environment for aquatic creatures by providing means to naturally circulate and cleanse the water thus encouraging biological growth and preventing the eutrophication of that body of water.
